• Compile Assembly Output generated by VC++?

  - by SDD

  I have a simple hello world C program and compile it with /FA. As a consequence, the compiler also generates the corresponding assembly listing. Now I want to use masm/link to assemble an executable from the generated .asm listing. The following command line yields 3 linker errors: \masm32\bin\ml /I"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include" /c /coff asm_test.asm \masm32\bin\link /SUBSYSTEM:CONSOLE /LIBPATH:"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\lib" asm_test.obj indicating that the C-runtime functions were not linked to the object files produced earlier: asm_test.obj : error LNK2001: unresolved external symbol @__security_check_cookie@4 asm_test.obj : error LNK2001: unresolved external symbol _printf LINK : error LNK2001: unresolved external symbol _wmainCRTStartup asm_test.exe : fatal error LNK1120: 3 unresolved externals Here is the generated assembly listing ; Listing generated by Microsoft (R) Optimizing Compiler Version 15.00.30729.01 TITLE c:\asm_test\asm_test\asm_test.cpp .686P .XMM include listing.inc .model flat INCLUDELIB OLDNAMES PUBLIC ??_C@_0O@OBPALAEI@hello?5world?$CB?6?$AA@ ; `string' EXTRN @__security_check_cookie@4:PROC EXTRN _printf:PROC ; COMDAT ??_C@_0O@OBPALAEI@hello?5world?$CB?6?$AA@ CONST SEGMENT ??_C@_0O@OBPALAEI@hello?5world?$CB?6?$AA@ DB 'hello world!', 0aH, 00H ; `string' CONST ENDS PUBLIC _wmain ; Function compile flags: /Ogtpy ; COMDAT _wmain _TEXT SEGMENT _argc$ = 8 ; size = 4 _argv$ = 12 ; size = 4 _wmain PROC ; COMDAT ; File c:\users\octon\desktop\asm_test\asm_test\asm_test.cpp ; Line 21 push OFFSET ??_C@_0O@OBPALAEI@hello?5world?$CB?6?$AA@ call _printf add esp, 4 ; Line 22 xor eax, eax ; Line 23 ret 0 _wmain ENDP _TEXT ENDS END I am using the latest masm32 version (6.14.8444).

• How to deploy SQL Reporting 2005 when Data Sources are locked?

  - by spoulson

  The DBAs here maintain all SQL Server and SQL Reporting servers. I have a custom developed SQL Reporting 2005 project in Visual Studio that runs fine on my local SQL Database and Reporting instances. I need to deploy to a production server, so I had a folder created on a SQL Reporting 2005 server with permissions to upload files. Normally, a deploy from within Visual Studio is all that is needed to upload the report files. However, for security purposes, data sources are maintained explicitly by DBAs and stored in a separated locked down common folder on the reporting server. I had them create the data source for me. When I attempt to deploy from VS, it gives me the error "The item '/Data Sources' already exists." I get this whether I'm deploying the whole project or just a single report file. I already set OverwriteDataSources=false in the project properties. The TargetServer URL and folder are verified correct. I suppose I could copy the files manually, but I'd like to be able to deploy from within VS. What could I be doing wrong?

• Uncompress a TIFF file without going through BufferedImage

  - by Gert

  I am receiving large size CCITT Group 4 compressed TIFF files that need to be written elsewhere as uncompressed TIFF files. I am using the jai_imageio TIFF reader and writer to do that and it works well as long as the product _width * height_ of the image fits in an integer. Here is the code I am using: TIFFImageReaderSpi readerSpi= new TIFFImageReaderSpi(); ImageReader imageReader = readerSpi.createReaderInstance(); byte[] data = blobManager.getObjectForIdAndVersion(id, version); ImageInputStream imageInputStream = ImageIO.createImageInputStream(data); imageReader.setInput(imageInputStream); TIFFImageWriterSpi writerSpi = new TIFFImageWriterSpi(); ImageWriter imageWriter = writerSpi.createWriterInstance(); ImageWriteParam imageWriteParam = imageWriter.getDefaultWriteParam(); imageWriteParam.setCompressionMode(ImageWriteParam.MODE_DISABLED); //bufferFile is created in the constructor ImageOutputStream imageOutputStream = ImageIO.createImageOutputStream(bufferFile); imageWriter.setOutput(imageOutputStream); //Now read the bitmap BufferedImage bufferedImage = imageReader.read(0); IIOImage iIOImage = new IIOImage(bufferedImage, null, null); //and write it imageWriter.write(null, iIOImage, imageWriteParam); Unfortunately, the files that I receive are often very large and the BufferedImage cannot be created. I have been trying to find a way to stream from the ImageReader directly to the ImageWriter but I cannot find out how to do that. Anybody with a suggestion?

• Best way to organize filetype settings in .vim and .vimrc?

  - by dimatura

  I'm going through my vim dotfiles to tidy them up. I've noticed that through time I've added various filetype specific settings in various inconsistent ways. Let's suppose I'm customizing for Python: au BufRead,BufNewfFile *.py (do something). I don't like this because some Python files might not have the .py termination. au FileType python (do something). This seems a better option because it doesn't depend on the file having the .py termination. The drawback is that Vim doesn't know about some filetypes. I can make Vim recognize additional filetypes, but I also have various inconsistent ways of doing it: a .vim/filetype.vim file, another in .vim/after/filetype.vim and various set filetype commands in .vimrc. Add a .vim/ftplugin/python.vim file with filetype specific settings. I understand the $VIMRUNTIME/ftplugin/python.vim can override whatever settings I make here. One problem is that I'm not sure how this interacts with .vim/filetype.vim and .vim/after/filetype.vim. Add a .vim/after/ftplugin/python.vim. I understand that this is loaded after $VIMRUNTIME/ftplugin/python.vim so it can overwrite settings from there. As in the previous method I'm not sure how it interacts with the filetype.vim files. So I have at least four ways of doing this, not mentioning syntax files and filetype-specific plugins. It seems to me the best way to do this is to put my filetype specific settings in after/ftplugin so they don't get overwritten, and filetypes.vim in after for the same reason. However, before I proceed I'd like to ask if anyone has suggestions about the best way to deal with filetype specific settings.

• Module based web project directory layout with git and symlinks

  - by karlthorwald

  I am planning my directory structure for a linux/apache/php web project like this: Only www.example.com/webroot/ will be exposed in apache www.example.com/ webroot/ index.php module1/ module2/ modules/ module1/ module1.class.php module1.js module2/ module2.class.php module2.css lib/ lib1/ lib1.class.php the modules/ and lib/ directory will only be in the php path. To make the css and js files visible in the webroot directory I am planning to use symlinks. webroot/ index.php module1/ module1.js (symlinked) module2/ module2.css (symlinked) I tried following these principles: layout by modules and libraries, not by file type and not by "public' or 'non public', index.php is an exception. This is for easier development. symlinking files that need to be public for the modules and libs to a public location, but still mirroring the layout. So the module structure is also visible in the resulting html code in the links, which might help development. How will git handle the symlinking of the single files correctly, is there something to consider? When it comes to images I will need to link directories, how to handle that with git? modules/ module3/ module3.class.php img/ img1.jpg img2.jpg img3.jpg They should be linked here: webroot/ module3/ img/ (symlinked ?) So this is a git and symlink question. But I would be interested to hear comments about the php layout, maybe you want to use the comment function for this.

• Django Image Upload: IOErrno2 Could not find path -- and yet it's saving the image there anyway?

  - by Rob

  I have an issue where the local version of django is handling image upload as expected but my server is not. Note: I am using a Django Container on MediaTemple.net (grid server) Here is my code. def view_settings(request): <snip> if request.POST: success_msgs = () mForm = MainProfileForm(request.POST, request.FILES, instance = mProfile) pForm = ChangePasswordForm(request.POST) eForm = ChangeEmailForm(request.POST) if mForm.is_valid(): m = mForm.save(commit = False) if mForm.cleaned_data['avatar']: m.avatar = upload_photo(request.FILES['avatar'], settings.AVATAR_SAVE_LOCATION) m.save() success_msgs += ('profile pictured updated',) <snip> def upload_photo(data,saveLocation): savePath = os.path.join(settings.MEDIA_ROOT, saveLocation, data.name) destination = open(savePath, 'wb+') for chunk in data.chunks(): destination.write(chunk) destination.close() return os.path.join(saveLocation, data.name) Here's where it gets whacky and I was hoping someone could shed a light on this error, because either a) it's the wrong error code, or b) something is happening with the file before it's completely handled. To recap, the file was actually uploaded to the server in the intended directory - and yet this err msg continues to persist.

• PHP import functions

  - by ninuhadida

  Hi, I'm trying to find the best pragmatic approach to import functions on the fly... let me explain. Say I have a directory called functions which has these files: array_select.func.php stat_mediam.func.php stat_mean.func.php ..... I would like to: load each individual file (which has a function defined inside) and use it just like an internal php function.. such as array_pop(), array_shift(), etc. Once I stumbled on a tutorial (which I can't find again now) that compiled user defined functions as part of a PHP installation.. Although that's not a very good solution because on shared/reseller hosting you can't recompile the PHP installation. I don't want to have conflicts with future versions of PHP / other extensions, i.e. if a function named X by me, is suddenly part of the internal php functions (even though it might not have the same functionality per se) I don't want PHP to throw a fatal error because of this and fail miserably. So the best method that I can think of is to check if a function is defined, using function_exists(), if so throw a notice so that it's easy to track in the log files, otherwise define the function. However that will probably translate to having a lot of include/require statement in other files where I need such a function, which I don't really like. Or possibly, read the directory and loop over each *.func.php file and include_once. Though I find this a bit ugly. The question is, have you ever stumbled upon some source code which handled such a case? How was it implemented? Did you ever do something similar? I need as much ideas as possible! :)

• are there java based auto-updating tools other than WebStart & Eclipse P2?

  - by DaddyB

  Hi, I am working on a java based application and we are looking to ease our deployment of updates. Up until now, we've always simply sent out new install packs & had the sysadmin's on our customer sites roll out the upgrades - painful for a large number of users. what I'd like to do is something similar to java webstart (or eclipse p2) - when the application starts, it checks for updates in a specified location and then downloads the updates prior to starting. But here's my problem - I want more control over what's done outside of the scope of plugins & jar files. For example: I'd like to be able to upate my JVM (we ship a modified version with additional security features). I need to install DLL's - possibly local to the jar files, sometimes to windows Occasiontally run MSI's to install windows components (e.g. printer drivers). I need to modify config files & the registry. I have found a few applications that support this (such as AppLifeUpdate at http://www.kineticjump.com/) but they tend to be .NET focused and it seems a bit perverse to introduce a .NET dependancy on a java application ;) I know I could write my own here, but if there is already a 3rd party library out there that supports this kind of facility, then it would make my life a lot easier. So, has anyone else had a similar problem & knows of some products I could look at? Thanks, Brian.

• Linker, Libraries & Directories Information

  - by m00st

  I've finished both my C++ 1/2 classes and we did not cover anything on Linking to libraries or adding additional libraries to C++ code. I've been having a hay-day trying to figure this out; I've been unable to find basic information linking to objects. Initially I thought the problem was the IDE (Netbeans; and Code::Blocks). However I've been unable to get wxWidgets and GTKMM setup. Can someone point me in the right direction on the terminology and basic information about #including files and linking files in a Cpp application? Basically I want/need to know everything in regards to this process. The difference between .dll, .lib, .o, .lib.a, .dll.a. The difference between a .h and a "library" (.dll, .lib correct?) I understand I need to read the compiler documentation I am using; however all compilers (that I know of) use linker and headers; I need to learn this information. Please point me in the right direction! :] So far on my quest I've found out: Linker links libraries already compiled to your project. .a files are static libraries (.lib in windows) .dll in windows is a shared library (.so in *nix) Thanks

• Code Organization Connundrum: Web Project With Multiple Supporting DLLs?

  - by Code Sherpa

  Hi. I am trying to get a handle on the best practice for code organization within my project. I have looked around on the internet for good examples and, so far, I have seen examples of a web project with one or multiple supporting class libraries that it references or a web project with sub-folders that follow its namespace conventions. Assuming there is no right answer, this is what I currently have for code organization: MyProjectWeb This is my web site. I am referencing my class libraries here. MyProject.DLL As the base namespace, I am using this DLL for files that need to be generally consumable. For example, my class "Enums" that has all the enumerations in my project lives there. As does class MyProjectException for all exception handling. MyProject.IO.DLL This is a grouping of maybe 20 files that handle file upload and download (so far). MyProject.Utilities.DLL ALl my common classes and methods bunched up together in one generally consumable DLL. Each class follows a "XHelper" convention such as "SqlHelper, AuthHelper, SerializationHelper, and so on... MyProject.Web.DLL I am using this DLL as the main client interface. Right now, the majority of class files here are: 1) properties (such as School, Location, Account, Posts) 2) authorization stuff ( such as custom membership, custom role, & custom profile providers) My question is simply - does this seem logical? Also, how do I avoid having to cross reference DLLs from one project library to the next? For example, MyProject.Web.DLL uses code from MyProject.Utilities.DLL and MyProject.Utilities.DLL uses code from MyProject.DLL. Is this solved by clicking on properties and selecting "Dependencies"? I tried that but still don't seem to be accessing the namespaces of the assembly I have selected. Do I have to reference every assembly I need for each class library? Responses appreciated and thanks for your patience.

• Return a list of imported Python modules used in a script?

  - by Jono Bacon

  Hi All, I am writing a program that categorizes a list of Python files by which modules they import. As such I need to scan the collection of .py files ad return a list of which modules they import. As an example, if one of the files I import has the following lines: import os import sys, gtk I would like it to return: ["os", "sys", "gtk"] I played with modulefinder and wrote: from modulefinder import ModuleFinder finder = ModuleFinder() finder.run_script('testscript.py') print 'Loaded modules:' for name, mod in finder.modules.iteritems(): print '%s ' % name, but this returns more than just the modules used in the script.

• Displaying progressbar using threading in win 32 applicaition!

  - by kiddo

  In my application I have a simple module were I will read files for some process that will take few seconds..so I thought of displaying a progress bar(using worker thread) while the files are in progress.I have created a thread (code shown below) and also I designed a dialog window with progress control.I used the function MyThreadFunction below to display the progressbar but it just shows only one time and disappears,I am not sure how to make it work.I tried my best inspite of the fact that I am new to threading. reading files void ReadMyFiles() { for(int i = 0; i < fileCount ; fileCount++) { CWinThread* myThread = AfxBeginThread((AFX_THREADPROC)MyThreadFunction,NULL); tempState = *(checkState + index); if(tempCheckState == NOCHECKBOX) { //my operations } else//CHECKED or UNCHECKED { //myoperation } myThread->PostThreadMessage(WM_QUIT,NULL,NULL); } } thread functions UINT MyThreadFunction(LPARAM lparam) { HWND dialogWnd = CreateWindowEx(0,WC_DIALOG,L"Proccessing...",WS_OVERLAPPEDWINDOW|WS_VISIBLE, 600,300,280,120,NULL,NULL,NULL,NULL); HWND pBarWnd = CreateWindowEx(NULL,PROGRESS_CLASS,NULL,WS_CHILD|WS_VISIBLE|PBS_MARQUEE,40,20,200,20, dialogWnd,(HMENU)IDD_PROGRESS,NULL,NULL); MSG msg; PostMessage( pBarWnd, PBM_SETRANGE, 0, MAKELPARAM( 0, 100 ) ); PostMessage(pBarWnd,PBM_SETPOS,0,0); while(PeekMessage(&msg,NULL,NULL,NULL,PM_NOREMOVE)) { if(msg.message == WM_QUIT) { DestroyWindow(dialogWnd); return 1; } AfxGetThread()->PumpMessage(); Sleep(40); } return 1; }

• how to find the last instance of a setting in a config file

  - by Glenn Kelley

  I am trying to figure out how to find the last entry of a string in multiple config files across a server. Each of the strings will be in the /home/***usernamewouldbehere/public_html/typo3conf/localconf.php file In short - the last entry in the config files will point to the database server the application is utilizing - and we need to know which accounts point to which db server. While I can run something like this - grep "$_db_host" /home/*/public_html/conf/localconf.php It does not really help much because it gives us way to much information ... and not what we really need. What i really need to know is the last entry of this string $_db_host = 'xx'; and to sort them out in an export file Since the config files may have multiple entries (example below) $_db_host = 'localhost'; $_db_host = '10.0.1.234'; It would be great to list in a file all of those that have the entry for 'localhost' and then list all of those that have the entry for '10.0.1.234' (or whichever server there may be there) but even if I need to do that manually that would be great. I am not sure how to get to it using Awk - ... and really stuck What I am hoping for is something that would be piped as follows db_host = localhost /home/username1/www/conf/localconf.php db_host = localhost / home/username2/public_html/conf/localconf.php db_host= '10.1.2.23' /home/username55/public_html/conf/localconf.php hoping that helps you help me :-)

• Finding a MIME type for a file on windows

  - by rmeador

  Is there a way to get a file's MIME type using some system call on Windows? I'm writing an IIS extension in C++, so it must be callable from C++, and I do have access to IIS if there is some functionality exposed. Obviously, IIS itself must be able to do this, but my googling has been unable to find out how. I did find this .net related question here on SO, but that doesn't give me much hope (as neither a good solution nor a C++ solution is mentioned there). I need it so I can serve up dynamic files using the appropriate content type from my app. My plan is to first consult a list of MIME types within my app, then fall back to the system's MIME type listing (however that works; obviously it exists since it's how you associate files with programs). I only have a file extension to work with in some cases, but in other cases I may have an actual on-disk file to examine. Since these will not be user-uploaded files, I believe I can trust the extension and I'd prefer an extension-only lookup solution since it seems simpler and faster. Thanks!

• Mix Audio tracks with offset in SOX

  - by Laramie

  From ASP.Net, I am using FFMPEG to convert flv files on a Flash Media Server to wavs that I need to mix into a single MP3 file. I originally attempted this entirely with FFMPEG but eventually gave up on the mixing step because I don't believe it it possible to combine audio only tracks into a single result file. I would love to be wrong. I am now using FFMPEG to access the FLV files and extract the audio track to wav so that SOX can mix them. The problem is that I must offset one of the audio tracks by a few seconds so that they are synchronized. Each file is one half of a conversation between a student and a teacher. For example teacher.wav might need to begin 3.3 seconds after student.wav. I can only figure out how to mix the files with SOX where both tracks begin at the same time. My best attempt at this point is: ffmpeg -y -i rtmp://server/appName/instance/student.flv -ac 1 student.wav ffmpeg -y -i rtmp://server/appName/instance/teacher.flv -ac 1 teacher.wav sox -m student.wav teacher.wav combined.mp3 splice 3.3 These tools (FFMEG/SoX) were chosen based on my best research, but are not required. Any working solution would allow an ASP.Net service to input the two FMS flvs and create a combined MP3 using open-source or free tools.

• How to remove Modules from a Intellij Maven Project permanently?

  - by herpnderpn

  I am currently working on a larger scale Maven-based project in IntelliJIdea 12.1.6 Ultimate. I have been working with IntelliJIdea since about 5 months. An included module has dependencies on another module. The dependent module's source was also part of my project until recently. Since I removed the dependent module from my project, I get compile errors whenever I am trying to compile the source without maven. The pom.xml of removed modules in Intellij seem to be placed onto the Settings-Maven-Ignored Files. I cant seem to remove it from there, only check or uncheck it. It's not possible to include the module again since IntelliJ will say its still under Ignored Files. 2 ways allow me to compile again: Uncheck the pom from Ignored files, which will include the module again in my project. Or delete the source of the dependent project, so my project will load the dependent module from the maven repository. But whenever I update my project from svn, the source of the dependent module is restored (I don't know why this even happens since its not part my project) and the cycle begins anew. I googled this for a while since it gets really annoying. It became a problem with several excluded modules. I could rebuild the intellij-project but since a lot of IntelliJ settings were made (not related to the problem) I would rather solve this. Any help is appreciated, I guess I must be missing something

• How to replace custom IDs in the order of their appearance with a shell script?

  - by Péter Török

  I have a pair of rather large log files with very similar content, except that some identifiers are different between the two. A couple of examples: UnifiedClassLoader3@19518cc | UnifiedClassLoader3@d0357a JBossRMIClassLoader@13c2d7f | JBossRMIClassLoader@191777e That is, wherever the first file contains UnifiedClassLoader3@19518cc, the second contains UnifiedClassLoader3@d0357a, and so on. I want to replace these with identical IDs so that I can spot the really important differences between the two files. I.e. I want to replace all occurrences of both UnifiedClassLoader3@19518cc in file1 and UnifiedClassLoader3@d0357a in file2 with UnifiedClassLoader3@1; all occurrences of both JBossRMIClassLoader@13c2d7f in file1 and JBossRMIClassLoader@191777e in file2 with JBossRMIClassLoader@2 etc. Using the Cygwin shell, so far I managed to list all different identifiers occurring in one of the files with grep -o -e 'ClassLoader[0-9]*@[0-9a-f][0-9a-f]*' file1.log | sort | uniq However, now the original order is lost, so I don't know which is the pair of which ID in the other file. With grep -n I can get the line number, so the sort would preserve the order of appearance, but then I can't weed out the duplicate occurrences. Unfortunately grep can not print only the first match of a pattern. I figured I could save the list of identifiers produced by the above command into a file, then iterate over the patterns in the file with grep -n | head -n 1, concatenate the results and sort them again. The result would be something like 2 ClassLoader3@19518cc 137 ClassLoader@13c2d7f 563 ClassLoader3@1267649 ... Then I could (either manually or with sed itself) massage this into a sed command like sed -e 's/ClassLoader3@19518cc/ClassLoader3@2/g' -e 's/ClassLoader@13c2d7f/ClassLoader@137/g' -e 's/ClassLoader3@1267649/ClassLoader3@563/g' file1.log > file1_processed.log and similarly for file2. However, before I start, I would like to verify that my plan is the simplest possible working solution to this. Is there any flaw in this approach? Is there a simpler way?

• How do I target a div without a class or id but with all these specific style-attributes

  - by Ben

  I'm restyling a certain page where I don't have access to all the source-HTML. So I'm left over with some hard to target elements within a page I need removed. For example the page is swamped with <div style="float: left; width: 10.25px; height: 284px;"></div>. To get rid of them I tried this in CSS: div[style="float: left; width: 10.25px; height: 284px;"] { display:none !important; } I'd like to fix this using CSS, because the the HTML that needs to be removed is updated using ajax. How do I target a div without a class or id but with all these specific style-attributes? Some more of the source-code (took a while to organize the parsed source): <div> <span class="Block BigPhotoList_Block"> <span class="Photo BigPhotoList_Photo" style="height: 200px"> <a href="/Webwinkel-Product-83760187/Le-Coq-Sportif-Angers-Low.html.html"> <span style="background-image:url(http://61955.static.securearea.eu/Files/2/61000/61955/ProductPhotos/MaxContent/144036303.jpg);" class="Canvas BigPhotoList_Canvas" title="Le-Coq-Sportif-Angers-Low"></span> </a> </span> <span class="Title BigPhotoList_Title"> <a href="/Webwinkel-Product-83760187/Le-Coq-Sportif-Angers-Low.html.html"> Le Coq Sportif Angers Low </a> </span> <span class="Price BigPhotoList_Price" style="font-size: 120%;"> € 89,95 </span> </span> <div style="float: left; width: 10.25px; height: 284px; border-right: 1px dashed #A0A0A0;" class="BigPhotoList_Stippel"></div> <div style="float: left; width: 10.25px; height: 284px;"></div> <span class="Block BigPhotoList_Block"> <span class="Photo BigPhotoList_Photo" style="height: 200px"> <a href="/Webwinkel-Product-83760185/Le-Coq-Sportif-Auveurne-Low.html"> <span style="background-image:url(http://61955.static.securearea.eu/Files/2/61000/61955/ProductPhotos/MaxContent/144036301.jpg);" class="Canvas BigPhotoList_Canvas" title="Le-Coq-Sportif-Auveurne-Low"></span> </a> </span> <span class="Title BigPhotoList_Title"> <a href="/Webwinkel-Product-83760185/Le-Coq-Sportif-Auveurne-Low.html"> Le Coq Sportif Auveurne Low </a> </span> <span class="Price BigPhotoList_Price" style="font-size: 120%;"> € 79,95 </span> </span> <div style="float: left; width: 10.25px; height: 284px; border-right: 1px dashed #A0A0A0;" class="BigPhotoList_Stippel"></div> <div style="float: left; width: 10.25px; height: 284px;"></div> <span class="Block BigPhotoList_Block"> <span class="Photo BigPhotoList_Photo" style="height: 200px"> <a href="/Webwinkel-Product-83760191/Le-Coq-Sportif-Bordeaux-Low.html"> <span style="background-image:url(http://61955.static.securearea.eu/Files/2/61000/61955/ProductPhotos/MaxContent/144036307.jpg);" class="Canvas BigPhotoList_Canvas" title="Le-Coq-Sportif-Bordeaux-Low"></span> </a> </span> <span class="Title BigPhotoList_Title"> <a href="/Webwinkel-Product-83760191/Le-Coq-Sportif-Bordeaux-Low.html"> Le Coq Sportif Bordeaux Low </a> </span> <span class="Price BigPhotoList_Price" style="font-size: 120%;"> € 99,95 </span> </span> <span class="Block BigPhotoList_Block"> <span class="Photo BigPhotoList_Photo" style="height: 200px"> <a href="/Webwinkel-Product-83760181/Le-Coq-Sportif-Cannet-Low.html"> <span style="background-image:url(http://61955.static.securearea.eu/Files/2/61000/61955/ProductPhotos/MaxContent/144036297.jpg);" class="Canvas BigPhotoList_Canvas" title="Le-Coq-Sportif-Cannet-Low"></span> </a> </span> <span class="Title BigPhotoList_Title"> <a href="/Webwinkel-Product-83760181/Le-Coq-Sportif-Cannet-Low.html"> Le Coq Sportif Cannet Low </a> </span> <span class="Discount BigPhotoList_Discount" style="font-size: 120%;"> € 99,95 </span> <span class="Price BigPhotoList_Price" style="font-size: 120%;"> € 94,95 </span> </span> <div style="float: left; width: 10.25px; height: 284px; border-right: 1px dashed #A0A0A0;" class="BigPhotoList_Stippel"></div> <div style="float: left; width: 10.25px; height: 284px;"></div> <span class="Block BigPhotoList_Block"> <span class="Photo BigPhotoList_Photo" style="height: 200px"> <a href="/Webwinkel-Product-83760183/Le-Coq-Sportif-Rodez-Low.html"> <span style="background-image:url(http://61955.static.securearea.eu/Files/2/61000/61955/ProductPhotos/MaxContent/144036299.jpg);" class="Canvas BigPhotoList_Canvas" title="Le-Coq-Sportif-Rodez-Low"></span> </a> </span> <span class="Title BigPhotoList_Title"> <a href="/Webwinkel-Product-83760183/Le-Coq-Sportif-Rodez-Low.html"> Le Coq Sportif Rodez Low </a> </span> <span class="Price BigPhotoList_Price" style="font-size: 120%;"> € 99,95 </span> </span> <div style="float: left; width: 10.25px; height: 284px; border-right: 1px dashed #A0A0A0;" class="BigPhotoList_Stippel"></div> <div style="float: left; width: 10.25px; height: 284px;"></div> <span class="Block BigPhotoList_Block"> <span class="Photo BigPhotoList_Photo" style="height: 200px"> <a href="/Webwinkel-Product-83760189/Le-Coq-Sportif-Sedan-Low.html"> <span style="background-image:url(http://61955.static.securearea.eu/Files/2/61000/61955/ProductPhotos/MaxContent/144036305.jpg);" class="Canvas BigPhotoList_Canvas" title="Le-Coq-Sportif-Sedan-Low"></span> </a> </span> <span class="Title BigPhotoList_Title"> <a href="/Webwinkel-Product-83760189/Le-Coq-Sportif-Sedan-Low.html"> Le Coq Sportif Sedan Low </a> </span> <span class="Discount BigPhotoList_Discount" style="font-size: 120%;"> € 109,95 </span> <span class="Price BigPhotoList_Price" style="font-size: 120%;"> € 99,95 </span> </span> </div>

• Raw types and subtyping

  - by Dmitrii

  We have generic class SomeClass<T>{ } We can write the line: SomeClass s= new SomeClass<String>(); It's ok, because raw type is supertype for generic type. But SomeClass<String> s= new SomeClass(); is correct to. Why is it correct? I thought that type erasure was before type checking, but it's wrong. From Hacker's Guide to Javac When the Java compiler is invoked with default compile policy it performs the following passes: parse: Reads a set of *.java source files and maps the resulting token sequence into AST-Nodes. enter: Enters symbols for the definitions into the symbol table. process annotations: If Requested, processes annotations found in the specified compilation units. attribute: Attributes the Syntax trees. This step includes name resolution, type checking and constant folding. flow: Performs data ow analysis on the trees from the previous step. This includes checks for assignments and reachability. desugar: Rewrites the AST and translates away some syntactic sugar. generate: Generates Source Files or Class Files. Generic is syntax sugar, hence type erasure invoked at 6 pass, after type checking, which invoked at 4 pass. I'm confused.

• generating and unmarshalling java classes while unmarshalling input contains a DTD

  - by Hans Westerbeek

  Hi, For a Spring-based project, I have the following situation to solve: I have XML files coming in whose contents I will have to parse at runtime. Those XML files come with a DTD reference. I need to generate the classes that the unmarshaller churns out using the right at build time, using the Maven2 plugin for the unmarshalling library of choice. This is also not very hard to do, once I have generated an XSD from the DTD. I want to use spring-oxm's UnMarshaller interface to do the unmarshalling at runtime. This I understand how to do. The xml files come in with a DTD reference, and all unmarshalling libraries out there want to do unmarshalling based on an XSD. Now, as described in the castor documentation, I can convert the DTD to an XSD and keep it on the classpath. However, when an actual XML file comes into the system it will still have that DTD reference at the top, and there's nothing I can really do about that (except for string replacing which feels hacky in this case). Will this cause the unmarshaller, like Castor to fail? Am I right in suspecting that this DTD reference will cause the unmarshalling to fail? Could I do pure DTD-based unmarshalling? Or can this somehow be prevented by providing detailed configuration to the unmarshaller? Until now, I have tried castor, xmlbeans and xstream. Which would fit my purposes best? Has anyone else been in this situation? Did you also end up just doing manual DOM or SAX parsing?

• Granite DS Actionscript Code Generation Ant cannot find class error

  - by Roaders

  I am trying to get my Ant build to run the granite DS Actionscript code generation task and am running into some problems. At the moment I am getting this error: BUILD FAILED C...\build.xml:62: Could not load Java class file: SampleDTOOne.class So the .class files are obviously being found. I am not however sure if this error means that the it cannot load the .class file or that it cannot find the actual java source code. My Ant task definition looks like this: <classpath> <pathelement location="C.../src/packages/" /> </classpath> <fileset dir="${base.build.dir}/jc/classes/gpbit/packageName"> <include name="*.class" /> </fileset> </gas3> I have tried many different values for the classpath but cannot get anythign to work. I do not like the path that I am using to find the .class files but again at the moment this is the only one I can get to work. None of the variables seem to make it any easier to get to this location. The fileset is definitely working as it definitely found the .clas files to include the name in the error message. More detailed error message: [gas3] Using output dir: C...trunk\plugin\build/etc/src/as3 [gas3] Using classpath: C...\trunk\plugin\src\packages [gas3] Loading all Java classes referenced by inner fileset(s) { [gas3] java.lang.ClassNotFoundException: SampleDTOOne [gas3] at org.apache.tools.ant.AntClassLoader.findClassInComponents(AntClassLoader.java:1361) any help much appreciated

• How can I access mainframe data with .Net applications and SQL Queries?

  - by orandov

  We have a large amount of data stored on an IBM mainframe using VSAM files. A lot of this data is dropped on the network every night in the form of text files to be processed and dumped into FoxPro and SQL Server databases. There are also many text files produced nightly by custom applications that get uploaded to the mainframe to keep everything in sync. Keeping the everything in sync is very tricky, to say the least. We are not getting rid of the mainframe any time soon and we would like to replace all the nightly batch processing with real time access to the mainframe data. We would like to be able to: Read data directly from the mainframe and produce reports based on it. Possibly using SQL queries. Read and Write data from custom .Net applications. We are not looking for a new platform to interface with the mainframe like Information Builders offers. We don't want to build application modules or reports with new "Business Intelligence" tools. We already know how to generate reports and write custom applications using SQL,.Net, Visual Studio, etc. All we are looking for is some sort of adapter to connect to our mainframe data. Any ideas are appreciated.

• How to show the progressbar using threading functionality in win32?

  - by kiddo

  In my application I have a simple module were I will read files for some process that will take few seconds..so I thought of displaying a progress bar(using worker thread) while the files are in progress.I have created a thread (code shown below) and also I designed a dialog window with progress control.I used the function MyThreadFunction below to display the progressbar but it just shows only one time and disappears,I am not sure how to make it work.I tried my best inspite of the fact that I am new to threading.Please help me with this friends. reading files void ReadMyFiles() { for(int i = 0; i < fileCount ; fileCount++) { CWinThread* myThread = AfxBeginThread((AFX_THREADPROC)MyThreadFunction,NULL); tempState = *(checkState + index); if(tempCheckState == NOCHECKBOX) { //my operations } else//CHECKED or UNCHECKED { //myoperation } myThread->PostThreadMessage(WM_QUIT,NULL,NULL); } } thread functions UINT MyThreadFunction(LPARAM lparam) { HWND dialogWnd = CreateWindowEx(0,WC_DIALOG,L"Proccessing...",WS_OVERLAPPEDWINDOW|WS_VISIBLE, 600,300,280,120,NULL,NULL,NULL,NULL); HWND pBarWnd = CreateWindowEx(NULL,PROGRESS_CLASS,NULL,WS_CHILD|WS_VISIBLE|PBS_MARQUEE,40,20,200,20, dialogWnd,(HMENU)IDD_PROGRESS,NULL,NULL); MSG msg; PostMessage( pBarWnd, PBM_SETRANGE, 0, MAKELPARAM( 0, 100 ) ); PostMessage(pBarWnd,PBM_SETPOS,0,0); while(PeekMessage(&msg,NULL,NULL,NULL,PM_NOREMOVE)) { if(msg.message == WM_QUIT) { DestroyWindow(dialogWnd); return 1; } AfxGetThread()->PumpMessage(); Sleep(40); } return 1; }
